Carrick actively involved his students in his commissions, encouraging and seeking out opportunities for their work. The unicorn at the top of the North Berwick memorial was by Phyllis Bone, one of Carrick's students and a near contemporary who remained a close friend. This unicorn was her first commission at the age of 25 and she went on to establish an international reputation as an animal sculptor with works including the Lion and Unicorn at the entrance to the Scottish National War Memorial in Edinburgh Castle (see Students)
The North Berwick war memorial was designed by local architect James Richardson who had served in the Great War. The mercat cross style memorial was fitting for the commemoration of the citizens of an ancient royal burgh. Carrick executed the work including the burgh Coat of Arms for the front panel.
